0F AURORA, ILLINOIS, A GORPORATIONJOF TROLLEY-TRACK.

To all whom it may concern:

Be it known that I, PETER L. HOFFMAN, a citizen of the United States, residing at Aurora,in the county of Kane and State of Illinois, have invented certain new and use ful Improvements in 1 Trolley-Tracks, of which the following is, a specification, reference being had to the accompanying drawmgs. p y This invention relates to improvements in trolly-tracks designed more particularly for door-hangers employed in connection with sliding doors located in positions exposed to the weather. With tracks so located, it is customary to provide a guard or shield over the track to protect it and the wheeled carriage that runsthereon and from which the door is suspended.

It is the object of my invention to provide a construction wherein the track rails and the supporting brackets therefor can be made of pieces of sheet-steel over which, and resting upon the brackets and conforming to the shape thereof, is a sheet-metal guard or shield, said track-rails, brackets and guard or shield being all secured together so as to form a single structure capable of being secured in place as a unit.

accomplish this stated object by the construction shown in the drawing and hereinafter specifically described.

That which I believe to be new will be set forth in the claims.

In the drawings,--Figure 1 is a perspective view of the track-rails and their attaching brackets,the guard or shield being removed. The rivets that are used for holding the guard or shield to the brackets and track are shown in section. Fig. 2 is a similar view but showing the guard or shield secured in place.

Referring to the two figuresof the drawings, in which corresponding parts are inclicated by like reference characters, 7) indicates a rear bracket-member formed of a straight piece of sheet-metal and adapted to rest against a wall or other suitable support. 6 indicates the front member of the bracket, which is also formed from a piece of sheetmetal. This member 6 has a short vertical wall-section 6 which lies against the rear member 5, an inclined section 6", and a vertical wall-section 6, which latter stands far Specification of Letters Patent.

enough removed from the rear bracketmember 5 to receive, between them the spacedapart tracks 7-7. While the bracket-members 5 and6 are formed separately as shown, yet it is evident thatif de sired they might be made from a single plece of material. In the construction shown, the two members are secured together by rivets 8. The track proper; is

formed of the two parallel rails 7-7, each: 1

formed, in the construction shown, of an angle-iron, the vertical walls of which rest against the inner faces of the bracket-members and are secured thereto in any appropriate manner,rivets 9 being used, as

shown. 10 indicates a guard or shield made I of sheet-metal and extending over the track and brackets so as to effectually cover them.

This guard or shield is bent to conform to the bracket-member 6, upon a plurality of which brackets, arranged at intervals, it rests and is secured. It has a short vertical wallsection 10, an inclined section 10', and a vertical wall-section 10 that bear against the bracket sections 6, 6", and 6, respectively, and at its upper portion it is bent to form a narrow flange l0 that will extend over the upper edges ofeach two bracketmembers 5 and 6. 10 indicates an out turned extension of the guard or shield below the track, which acts to deflect water away from the door that is suspended below the track. The whole is secured firm y in place upon the bracket-member 6, the securing means shown being the rivets 8 and 9 before mentioned. In place of such rivets, the parts may be secured together, if desired, by electrical spot-welding. The guard or shield, in addition to serving as a housing to protect the track and the carriage that runs thereon from the weather, serves also to connect the several sustaining brackets, each formed of the members 5 and 6, together, and as such brackets are spaced at a considerable distance from each other, the structure as a whole is light in weight and at the same time very strong. Furthermore, by having the guard or shield 10 connected with the brackets, the complete device can be very quickly and easily secured in place by a heai y screw or bolt passed through the opening 11 that extends through the parts guard or shield as a.

t track-rail secured to each of said members,

a guard or shield corresponding in shape to the shape of one of the bra'c'ket members and extending over and secured to such 'members.

i t 2. In a trolley-track, the combination With a track-rail and a securing bracket therefor comprising a vertical attaching section, an inclined section and a second vertica *section', of a guard or shield corresponding "in shape to the shape 'of the bracket and resting thereon, and means for securing said guard or shield tosaid bracket.

3. In a trolley-track, the combination with a pair of track-rails and a plurality of securing brackets therefor, said brackets being spaced a distance apart and each comprising a rear member and a front member, said front member having a Vertical section resting against said rear member, an inclined section and a second vertical section, of a guard or shield -'c'0'rresponding,in shape to the shape of the front members of the brackets and resting thereon,-ancl1neans for securing said guard or shield't'o said brackets.
